Cointreau

From Jason Wilson:

Margarita

1 1/2 ounce tequila
1 ounce Cointreau
1 ounce lime juice


Cosmopolitan

1 1/2 ounce vodka
1 ounce Cointreau
3/4 ounce cranberry juice
1/4 ounce lime juice

(Wilson calls for 1/2 ounce each lime juice and cranberry juice, but it was too limey in my opinion.  Also, he calls for a citrus vodka, which I don't have.  This was pretty good with the vodka that Mo brought to the BC students seminar (alas, I did not notice the brand), and not bad with the rotgut vodka we have at home, which is otherwise only good for cooking.)
